Your experience here really depends on the team you're on. I personally had a terrible experience with my boss and team and since I was an entry-level employee, my concerns were not addressed or recognized appropriately with both the operations teams or HR.
Additionally, I feel as though big-agency lifestyle does not foster room for professional growth for entry-level employees as there is such high-turnover in the industry. Entry-levelers are often looked down upon by senior staff in terms of speaking up to insert their ideas. If you are an AAE in consumer, you're probably shipping product and organizing excels/decks for most of the time, rather than getting hands-on experience in PR.
